Despite morphine being the most medically significant opioid, larger quantities of codeine are consumed medically, most of it synthesized from morphine. Codeine has greater and more predictable oral bioavailability. Codeine is not reliably metabolised into its active form, morphine, by CYP2D6 due to the considerable amount of polymorphism. Many ...
Related to codeine in other ways are codoxime, thebacon, codeine-N-oxide (genocodeine), related to the nitrogen morphine derivatives as is codeine methobromide, and heterocodeine, which is a drug six times stronger than morphine and 72 times stronger than codeine due to a small re-arrangement of the molecule, namely moving the methyl group from ...
Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time." Russian Chemical Bulletin.
The definition encompassing "any illegal drug" was first recorded in 1926. Its first use as an adjective is first attested to c. 1600. [22] There are many different types of narcotics. The two most common forms of narcotic drugs are morphine and codeine. Both are synthesized from opium for medicinal use.
It combines "opium" + "-oid" meaning "opiate-like" ("opiates" being morphine and similar drugs derived from opium). The first scientific publication to use it, in 1963, included a footnote stating, "In this paper, the term, 'opioid', is used in the sense originally proposed by George H. Acheson (personal communication) to refer to any chemical ...

Detoxing is a first step towards sobriety. To overcome the inevitable pain of withdrawal from opiates without medication—going “cold turkey”—is excruciating. The ordeal may take a week or longer, and there is little relief from sleep deprivation, depression, and loss of bodily functions.
The methyl group that makes morphine into codeine can be removed or added back, or replaced with another functional group like ethyl and others to make codeine analogues of morphine-derived drugs and vice versa. Codeine analogues of morphine-based drugs often serve as prodrugs of the stronger drug, as in codeine and morphine, hydrocodone and ...
